Initial preparation

Install the supplied batteries by following the in-

structions in the "Battery replacement" section.

Connect the HI 1048B pH electrode to the BNC

plug on the top of the meter.

Taking measurements

• Turn the instrument ON.

• Remove the electrode protective cap, sub-

merge the tip (4cm/1.5") into the sample to

be tested and allow the reading to stabilize.

• Since pH readings are directly affected by

temperature, for accurate measurements,

follow the instructions for manual tempera-

ture compensation. If the temperature of

the sample is significally different from that

at which the electrode was stored, allow a

few minutes to reach thermal equilibrium.

Notes:

• Before taking any measurements:

- make sure the meter is calibrated.

- rinse the electrode thoroughly with some

of the sample to be tested, to avoid cross

contamination.

• After use, switch the instrument off, clean

the electrode with HI 70635 and/or HI 70636

solution (see "Accessories" section) and

then rinse with clean water. Pour a few

drops of HI 70300 storage solution in the

protective cap and replace it before storing

the electrode.

• It is recommended to always keep the elec-

trode wet.

Manual temperature compensation

• Press the "pH/°C SET" key to select the

manual temperature mode.

• Remove the protective cap on

the top of the meter to access

the trimmers.

• Measure the temperature of the

solution with the supplied

ChecktempC thermometer.

• Using the supplied screwdriver, adjust the

"T" trimmer to display the measured tem-

perature value, e.g. 15.0°C.

OPERATIONAL GUIDE

• Remove the electrode protective cap and

rinse with some pH 7.01 solution.

• Immerse the electrode tip (ap-

proximately 4cm/1.5") and the

ChecktempC thermometer in

pH 7.01 buffer solution.

• Stir gently and wait for the read-

ing to stabilize.

Note: Place the ChecktempC thermometer

close to the pH electrode.

• Record the buffer temperature (e.g. 10°C) and

adjust the "T" trimmer accordingly.

• Using the supplied screwdriver, adjust the

"pH7" trimmer until the meter displays the

pH value at the buffer temperature (see table),

e.g. pH 7.07 at 10°C.

• Rinse first with clean water and then with a

small amount of pH 3.00 buffer. Dip the elec-

trode and the ChecktempC into the pH 3.00

buffer, stir gently and wait for the reading to

stabilize.Record the buffer temperature and

adjust the "T" trimmer accordingly.

• Using the supplied screwdriver, adjust the

"pH3" trimmer until the meter displays the

pH value at the buffer temperature (see table),

e.g. pH 3.04 at 10°C.

The calibration is now complete.

CALIBRATION

When batteries become weak,

the "V" tag lights up on the dis-

play to alert the user that only a

few hours of working time is left.

If the battery level is low enough to cause erro-

neous readings, the Battery Error Prevention

System (BEPS) turns the meter off.

Battery replacement must only take place in a

non-hazardous area using 1.5V AA alkaline

type.

Unscrew the two screws on the

meter back, remove the battery

compartment cover and replace

all the four batteries with new

ones, while paying attention to

the correct polarity. Reattach the

cover and tighten the two

screws.
